Referring in detail to the drawings, it will be seen that 5 designates an elongated-platform upon one end of which is mounted a base 6. Rising from the base 6 are standards 1 5O 8, the upper ends of which are integral'with a horizontally disposed tubular member 9.

he base 6 issuitably secured to the platform 5. through the medium of bolt and nut means 7 extending through the base 6 and suitable slots provided therefor in the platform 5.

For moving the base 6 longitudinally of the platform 5 for adjusting the base 6 at any predetermined points on the platform '5 there is provided an elongated adjusting screw 10 which has a non-threaded end rotatable in a suitably apertured lug 11 formed on one end of the platform 5, the threaded end portion of the screw being threaded through an internally threaded portion 12 formed in one of the standards 8 at the lower end of the standard. A suitable lock nut13 engages the threaded portion of the screw 10 and bears against the lug 11. The tubular member 9 at one end thereof is counterbored to provide at said one end a suitable socket ld'adapted to 7 receive therein one end of an intake pipe 15 a portion of which is shownfragmentarily in Figures 1 and 2 of the drawings.

- A suitable packing ring 16 is disposed circumj acent the intake pipe 15 at the outer end of the socket 14. Suitable screws 17 are uti-' lized for retaining the packing ring 16 in position. At its opposite end the tubular member 19 is enlarged to provide an enlarged annular head 18. I The head 17 at the inner end thereof is provided with an annular recess 19 forming aninternal annular shoulder 20.

An intake transmitter member is rotatably mounted in the head 18 and said transmitter member comprises a tubular body portion 21 provided at its inner end with an annular flange projecting forwardly thereof, and said flange is provided with an annular groove for retaining therein an annular tongue formed at the inner end of the head 18 within the recess 19 providing somewhat of a packing structure between the tubular member 9 and body portion 21 of the transmitter as at 22,

Also arranged between the inner end" of the body 21 of said intake transmitter and adjacent portion of the tubular member 9, and located within the confines of the last referred to flange is a suitable packing ring 23.

Disposed about the body 21 of said transmitter and arranged between said body and the peripheral wall of the head 18 are suitable antifriction means comprising a pair of annular ball races at between which are suitably retained ball bearings 25. The said anti-friction means are retained in position between the shoulder 20 of the head and the outstanding annular flange 26 formed on the outer end of the body of said transmitter.

At said outer flanged end, the body of the transmitter is provided with a conical discharge mouth 27. At the last referred to end thereof the transmitter is provided with a concentric annular flange or extension 27' which receives within the confines thereof one end of the cylindrical portion 28 of an impeller designated generally by the reference character I. Inwardly from the flange 27 the body 21 of the transmitter is provided with an annular groove having arranged therein a suitable packing member or gasket 29 one face of which bears against the adjacent end of the impeller I providing a fluid tight connection between the impeller and transmitter.

The cylindrical body portion 28 of the impeller I merges at one end thereof into a conical body portion 30. which body portion 30 at its small st end merges into an axially disposed tubular neck 31. The impeller I has formed axially of the cylindrical portion 28 a hub 31' from which radiates a plurality of impeller blades 32.

The blades 32 are preferably of the construction and arrangement suggested, in Fig ures 2, 4 and 5, it being noted that the blades are preferably six in number an d. are somewhat segmental. or moon shaped and the ends of the blades integral with the hub 31 are arranged somewhat in overlapping relation with the forward ends of the blades welded or otherwise formed integral with the inner face of the cylindrical body portion 28.

The blades 32 are suitably spaced from one another and are disposed substantially at a forty-live degree angle relative to the horizontal axis of the hub 31 to provide therebetween passages disposed substantially obliquely relative to the horizontal axis of the propeller as suggested in Figure 2.

The flanged free end of the neck 31 is rotatable within the confines of an annular flange 34 that projects from one side of an internal annular shoulder 35 formed within the body portion of discharge transmitter designated generally by the reference character 37. At that end thereof, remote from the impeller I the body portion of the discharge transmitter 37 is provided with an outstanding annular flange 38.

Extending within said flanged end of the body 36 is the forward end of an enlarged head portion 39 of a discharge pipe 10.

For suitably supporting the pipe d0 in longitudinal alinement with the intake pipe 15 and tubular member 9 there is provided a base member 41 suitably anchored to the platform 5 as at 4-2. Rising from the base member ll is a pair of standards 4.3 that have formed integrally with the upper ends thereof a bearing seat 44.

A suitable bearing cap 15 is provided, and is suitably bolted to the seatl-l for retaining between said cap and seat an intermediate portion of the discharge pipe -10.

The discharge transmitter 37 is of course rotatably mounted on the outer end of the head 39 of said pipe 40. Said head 39 inwardly from the outer end thereof is provided with an annular groove 46 within which are arranged antifriction means in the nature of a caring 47 similar in every detail to the anti-friction means described as located in the head 18. A more detailed description of the anti-friction means 47 is therefore thought unnecessary.

The anti-friction means 47 is confined with in the groove 46 through the medium of the flange 38 on the adjacent end of the transmitter 37, as is apparent from a study of Figure 2.

That end of the head 39 which fits within I the body 36 of the discharge transmitter 37 is provided with an annular flange that in turn is provided with an annular groove receiving therein an annular tongue formed on an adjacent face of the shoulder 35 thus providing somewhat of a tongue and groove connection -18 between said head and said transmitter.

Projecting from one face of the shoulder 35 and arranged within the confines of the said grooved flange of the head 39 is an annular flange 49 within the confines of which is a ranged a suitable gasket 50 interposed between the opposed faces of the head 39 and shoulder 35.

The shoulder 35 inwardly from the flanged extension 34 is also provided with an annular groove within which is arranged an annular packing member or gasket 51 one face of which bears against the flanged end of the neck 31 of the impeller I.

From the foregoing then it will be seen that suitable fluid tight connections are pro vided between the pipe 40, transmitter 37, and between the transmitter 37 and the impeller I, as well as between the impeller I and the intake transmitter.

The discharge transmitter 37 at that end remote from the flange 32 has formed integrally with the body 36 thereof an annular pulley wheel 52 into the interior of which extends a portion of the conical body 30 of said impeller I. Any suitable belt means designated generally by the reference character B and shown in broken lines in Figure 1 is trained over the pulley 52, said belt 13 lead ing from any suitable source of power for panying drawings. Obviously as the impel-,

ler I, and transmitters 37, 37 are simultaneously rotated, vacuum, due'to the position of the blades 32 is formed in the spaces between the blades 32 while the impeller is being speedily rotated. The Vacuum, notwithstanding the pressure of the atmosphere, causes the fluid to be drawn in through the intake pipe 15 and tubular member 9 through the intake transmitter 37 to discharge from the conical mouthed end 27 of said transmitter into the impeller I, the fluid passing between the blades 32, through the conical body an opening therethrough, one of said transmitters at one end of its body being provided with a relatively large discharge month, an impeller including a casing having a cylindrical part and a conical part, said cylindrical part on said casing at one end of the casing fitted within the mouth of said one transmitter, the other of said transmitters interiorly of its bod being provided with an annular shoulder aying a circular flange projecting therefrom, and the conical part of said impeller casing at its free end arranged within the confines of said flange and having an outstanding annular flange engaging with the first named flange and blades arranged within the cylindrical part of the impeller cas- GEORGE WALLACE,

portion 30 and'the tubular neck 31 of the impeller to pass from the discharge transmitter 37 into the discharge pipe 4L0 passing from the pipe 40 to any suitable container or mechanism provided therefor. In the operation of the device, the conical body portion of the impeller provides a cone-like compiler which serves as a reducer for the fluid or material passing from the impeller I into the discharge pipe 40.

When, because of wear, or any other reason it is desired to remove the impeller I to replace the same with a new one, it will be apparent that by rotating the adjusting screw 10, the base member 6 will be moved longitudinally of the platform 5 in a direction away from the base member 41 whereby the impeller I may be readily removed from between the transmitters 37 and 37 and, if desired the transmitters 37 and 37 may be subsequently removed for cleaning, repairing or for any other purpose.

For securing the impeller 1 between the transmitters 37 and 37 so as to be positioned directly between the intake pipe 15 and dis- 7 charge or outlet pipe lO-the reverse operation is obviously employed, that is when the impeller is so positioned the screw 10 is operated for moving the base 6 inwardly toward the base 41.

Even though I have herein shown and described the preferred embodiment of my invention, it is to be understood that the same is susceptible to changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having-thus described my invention, what I claim as new is:

A pump including in combination a pair of opposed rotatably mounted transmitters, each of said transmitters including a body having
